Sally Hansen Advanced Hard as Nails™, Clear Nail Strengthener, Includes Retinol and Nylon, Nourishing

I decided on day to actually learn what you are supposed to do with your nails correctly and decided to not just buy stuff from the dollar store anymore. That lead me down a deep rabbit hole about which products where best, the types of nail polish, undercoats, top-coats, gels, hardeners and AHHHhhhh! Suffice it to say I am more familiar and comfortable building a fire in my wood stove or fixing things around the house.I am also... kinda of cheap because I have brilliant children who will want to go to college someday and other things I am always saving up for.So, with all of that in mind I started the journey towards finding high quality but not too expensive clear coats. This was one of the 3 I bought and I am absolutely impressed! It lasts for weeks. I am pretty rough on my nails but this stuff just lasted and continued being shiny, smooth and keeping my nails happy.One thing I did notice which is probably just because I have never used anything like this before was that instead of breaking off in one big break like my nails normally do, with this on they flaked in layers or broke in smaller ways just at the tips. It didn't seem like it caused any negative issues because nails will always break eventually, but that was a change in how they reacted I noticed.So for the price and what it is the quality is there. It isn't too thick which is nice, and it dries quickly. Can't ask for much more for a basic hardener/clear coat.

I was skeptical about how well this polish would work, based on other reviews, but this has been a lifesaver for my nails. They had been growing in cracked/peeling no matter what I did. I was constantly cutting them as short as possible over and over again, hoping that the next time would be the time they’d finally grow back in healthily. However, within one use of this polish my nails have come back in with no splits and no cracks!I apply two coats each time. It usually lasts 1-2 weeks before the polish peels or chips and I have to reapply. My nails look healthy and shiny, even a full week after I’ve applied the polish. It’s been about a month since I started using this polish, I’ve applied coats 3 times, and my nails are finally healthy and long enough that I’ll be going for a manicure next week. I can’t recommend this polish enough. Don’t hesitate, get it.

This nail strengthener is very good. I would recommend this because since I got a cut on my nail, I put this on and it stuck together really fast. This is the most greatest product for the price. This is just like nail polish. This is especially good for sports. This product will not let your nail crack. This also makes your nails glossy. This is a five out of five stars. I do not regret buying this. The only bad part about this is just the substance just sometimes gets on the bottle. Everything else is on point

Truly does make a difference in hardness of my nails. They don’t break nearly as easily. It does smell pretty bad, so I recommend opening a window when using.

I loved this product the minute I put it onto my nails for the first time. I have somewhat fragile nails (they literally break sometimes just from tapping against a door a wrong way) after applying this polish my nails have been growing strong without a worry of breaking. I've put 3-4 layers; it dries super quick and makes my nails shine beautifully! I'd recommend trying this product out, you can't beat the price, and the more layers the better.

After many years wearing gel nails, I have decided to stop wearing them. As anyone who has worn gel nails knows, the process of filing down natural nails makes tour nails very thin and weak. I bought this nail hardener to help my nails as they grow out.After 2 weeks my nails are a bit stronger.

My nails were always splitting and I had to always file them short. I got this nail hardener and since I've benn using it, my nails havent split once. AND I am so proud to show off my nails, they are beautiful. Thank you, Sally Hanson

Smells terrible (like toxic chemicals), but a solid OG top coat. I continue to buy because it dries quickly, is easy to apply, and lasts.
